# Rust User API 文档
## 概述
这是一个使用 Rust 和 Axum 框架构建的用户管理 REST API。提供完整的用户 CRUD 操作和 JWT 身份认证功能。
## 基础信息
- **Base URL**: `http://localhost:3000`
- **Content-Type**: `application/json`
- **认证方式**: JWT Bearer Token
## 端点列表
### 基础端点
#### GET /
获取 API 欢迎信息
**响应示例**:
```json
{
"message": "欢迎使用 Rust User API",
"version": "0.1.0"
}
```
#### GET /health
健康检查端点
**响应示例**:
```json
{
"status": "healthy",
"timestamp": "2024-01-01T12:00:00Z"
}
```
### 用户管理
#### POST /api/users
创建新用户
**请求体**:
```json
{
"username": "string (3-50字符)",
"email": "string (有效邮箱)",
"password": "string (至少8字符)"
}
```
**成功响应** (201 Created):
```json
{
"id": "uuid",
"username": "testuser",
"email": "test@example.com",
"created_at": "2024-01-01T12:00:00Z"
}
```
**错误响应**:
- 400 Bad Request: 验证失败
- 409 Conflict: 用户名已存在
#### GET /api/users
获取所有用户列表
**成功响应** (200 OK):
```json
[
{
"id": "uuid",
"username": "testuser",
"email": "test@example.com",
"created_at": "2024-01-01T12:00:00Z"
}
]
```
#### GET /api/users/{id}
根据 ID 获取特定用户
**路径参数**:
- `id`: 用户 UUID
**成功响应** (200 OK):
```json
{
"id": "uuid",
"username": "testuser",
"email": "test@example.com",
"created_at": "2024-01-01T12:00:00Z"
}
```
**错误响应**:
- 404 Not Found: 用户不存在
#### PUT /api/users/{id}
更新用户信息
**路径参数**:
- `id`: 用户 UUID
**请求体**:
```json
{
"username": "string (可选, 3-50字符)",
"email": "string (可选, 有效邮箱)"
}
```
**成功响应** (200 OK):
```json
{
"id": "uuid",
"username": "newusername",
"email": "newemail@example.com",
"created_at": "2024-01-01T12:00:00Z"
}
```
**错误响应**:
- 400 Bad Request: 验证失败
- 404 Not Found: 用户不存在
#### DELETE /api/users/{id}
删除用户
**路径参数**:
- `id`: 用户 UUID
**成功响应** (204 No Content): 无响应体
**错误响应**:
- 404 Not Found: 用户不存在
### 身份认证
#### POST /api/auth/login
用户登录
**请求体**:
```json
{
"username": "string",
"password": "string"
}
```
**成功响应** (200 OK):
```json
{
"token": "jwt_token_string",
"user": {
"id": "uuid",
"username": "testuser",
"email": "test@example.com",
"created_at": "2024-01-01T12:00:00Z"
}
}
```
**错误响应**:
- 401 Unauthorized: 用户名或密码错误
- 404 Not Found: 用户不存在
## 错误响应格式
所有错误响应都遵循统一格式：
```json
{
"error": "错误描述信息",
"status": 400
}
```
### 常见错误码
- **400 Bad Request**: 请求参数验证失败
- **401 Unauthorized**: 认证失败或未提供认证信息
- **404 Not Found**: 请求的资源不存在
- **409 Conflict**: 资源冲突（如用户名已存在）
- **500 Internal Server Error**: 服务器内部错误
## 认证机制
API 使用 JWT (JSON Web Token) 进行身份认证。
### 获取 Token
通过 `POST /api/auth/login` 端点登录获取 JWT token。
### 使用 Token
在需要认证的请求中，在 Header 中添加：
```
Authorization: Bearer <your_jwt_token>
```
### Token 有效期
JWT token 有效期为 24 小时。
## 数据验证规则
### 用户名 (username)
- 长度：3-50 字符
- 必须唯一
### 邮箱 (email)
- 必须是有效的邮箱格式
- 例如：`user@example.com`
### 密码 (password)
- 最少 8 个字符
- 使用 bcrypt 进行哈希存储
## 使用示例
### 创建用户并登录
```bash
# 1. 创建用户
curl -X POST http://localhost:3000/api/users \
-H "Content-Type: application/json" \
-d '{
"username": "testuser",
"email": "test@example.com",
"password": "password123"
}'
# 2. 登录获取 token
curl -X POST http://localhost:3000/api/auth/login \
-H "Content-Type: application/json" \
-d '{
"username": "testuser",
"password": "password123"
}'
# 3. 使用 token 访问受保护的端点（未来功能）
curl -H "Authorization: Bearer <your_token>" \
http://localhost:3000/api/protected-endpoint
```
## 开发和测试
### 运行服务器
```bash
cargo run
```
### 运行测试
```bash
# 运行单元测试
cargo test
# 运行 API 集成测试
./test_api.sh
```
### 环境配置
复制 `.env.example` 到 `.env` 并修改配置：
```bash
cp .env.example .env
```
## 技术实现
- **Web 框架**: Axum 0.7
- **异步运行时**: Tokio
- **序列化**: Serde
- **密码哈希**: bcrypt
- **JWT**: jsonwebtoken
- **验证**: validator
- **日志**: tracing
## 后续计划
- [ ] 数据库持久化 (SQLite)
- [ ] API 分页支持
- [ ] 用户搜索和过滤
- [ ] 角色和权限管理
- [ ] API 限流
- [ ] OpenAPI/Swagger 文档
